The Underground Storage Tank (UST) Program is a major component of the Massachusetts groundwater resource protection effort. MassDEP implements federal requirements addressing registration and inspection of UST systems used to store petroleum fuels or hazardous substances. UST systems found to be leaking or not working properly must be repaired or replaced, and any resulting environmental damage assessed and cleaned up.

Note: The forms below currently remain in use. Replacement forms will be introduced in summer 2015
